Hi.
I wrote a bunch of methods to mock some components of openjump to do unit
tests and functional tests. I'm planning to use this knowledge to write an
external application using the openjump-api.
I spend several hours to figure out, how to mock them and hope to contribute
some of my code. As soon as I am back at work (monday) I'll try to post some
source code.
